Attention Andrea Acri I think Dr Frits Stall is very right. Dr Lokesh Chandra never had an email. But I have his new contact number. Please note it down; 91-11-26515800. I hope this works. You may also note down his postal address in case you do not have it; Prof Lokesh Chandra J-22 Hauz Khas Enclave New Delhi - 110016
